Powercuff on iOS 18 👀
You may have seen the FiveIconDock via LightSaber post earlier today. This is the same chain but with a new payload. (I am zeroxjf.)
I ported rpetrich's Powercuff into LightSaber. Pick a throttle level (off, nominal, light, moderate, heavy) and the chain injects into thermalmonitord, calling putDeviceInThermalSimulationMode: directly. The daemon reports that thermal level system-wide — Battery, Game Mode, CPU governor, etc.
All credit to rpetrich for the original tweak and the API. This just wires it into the chain instead of loading a dylib.
Since thermalmonitord survives respring, the throttle persists until a full reboot. To change levels, reboot and re-run with a new selection. I may look at avoiding daemon injection altogether to make clearing easier.
Test devices recommended. Chain success rate is ~60–70%; failures can cause resprings or kernel panics.
Not conventional tweak injection, this is JavaScript running inside the DarkSword exploit chain. Still pretty cool for "jailed" iOS 18. More to come as I think of what else could work in this limited environment.
